LDWF is responsible for monitoring and managing wild crawfish; the information below applies to the harvest of wild crawfish. The Louisiana Department of Agriculture, U.S. Department of Agriculture, and other agencies are responsible for farm-raised crawfish.
Legal Gear and Gear Requirements
You may use approved crawfish traps to harvest wild crawfish in Louisiana’s waters. Trap mesh must be a hexagon of 3/4-inch by 11/16-inch or larger, measured from wire to wire, not including any coating on the wire. The openings of trap flues and throats must not exceed two inches. These requirements allow small crawfish to escape the trap—small crawfish have little market value and are important to the population for breeding.
Seasons and Size and Possession Limits
There are no limits on season, size, or possession for commercial crawfish harvests. Harvest controls are not necessary as crawfish populations are productive, resilient, and influenced by environmental conditions, rather than fishing.
Wildlife Management Areas (WMAs) and Refuges
Commercial fishing is permitted in:
- Fort Polk (see fishing regulations posted at specific lakes)
